CLAIM OF PRIORITY

This application claims the benefit under 35 U.S.C. §119(a) of a Korean patent application filed on Oct. 21, 2013 in the Korean Intellectual Property Office and assigned Serial No. 10-2013-0125629, the entire disclosure of which is hereby incorporated by reference.

BACKGROUND

Field

The present disclosure relates to an electronic device, and more particularly, to a semiconductor device with a vertical stack configuration and an electronic device including the same.

Description of the Related Art

In today's electronic devices such as smart phones, tablet Personal Computers (PC), mobile phones, laptop PCs, netbook computers, Personal Digital Assistants (PDA), Portable Multimedia Players (PMP), Moving Picture Experts Group layer-3 (MP3) player, camera, and wearable devices, it is desirable to minimize the internal space occupied by semiconductor chips.

It is beneficial for a portable electronic device to consume a small amount of power so as to exhibit a long battery life between recharges. A modern portable device includes a high performance processor and memory device so as to perform a function (e.g., game playing, moving picture reproduction) requiring high performance.

In order to achieve high performance operation with low consumption power, various interface methods and package methods between a memory device and a processor included in the electronic device have been proposed. For example, in a progression from conventional two-dimensional (2D) configurations in which a memory device and a processor are disposed in a common (horizontal) plane, an application package method of three-dimensional (3D) fabrication technology that stacks a memory device and a processor in the vertical dimension has been developed. In such 3D fabrication technology, a Through Silicon Via (TSV) method is used. The TSV method improves performance over other interconnect methods by reducing data bandwidth and transmission speed deterioration (previously a variable on package design).

Further, a so-called wide I/O interface has been developed, which is an Input/Output (I/O) interface with many parallel paths. A wide I/O interface can be used with a low cost memory device accessed with a multi-channel method, and enables high speed data transmission. One example of a wide I/O interface is a 512-bit parallel interface, which is significantly wider than common 16-bit or 32-bit parallel interfaces in wide use today.

Conventionally, when stacking and packaging a memory device and a processor having different interfaces, a plurality of TSVs are necessary. In such a TSV method, stacked semiconductor chips are directly penetrated and thus when separate space for penetrating is allocated in the layout, a design area of a semiconductor chip decreases. Moreover, when penetrating, the semiconductor chips may be damaged, which leads to a problem of increased process cost.

SUMMARY

Disclosed herein is a semiconductor device using a universal memory bridge chip that can electrically connect semiconductor chips using a TSV and that can provide a compatible interface to the semiconductor chips having different kinds of interfaces. An electronic device including the semiconductor device is further disclosed.

In accordance with an aspect of the present disclosure, an electronic device includes: a communication module; an input module; a display; an interface; at least one sensor; a first memory; and a processor module, wherein the processor module includes at least one of: at least one dummy chip including at least one Through Silicon Via (TSV); at least one memory bridge including at least one TSV; at least one second memory connected to the at least one dummy chip and the at least one memory bridge and configured to exchange an electric signal through the at least one dummy chip and the at least one memory bridge; or at least one processor configured to exchange an electric signal through the at least one memory bridge. The at least one processor may transmit an electric signal to at least one of the communication module, input module, display, interface, at least one sensor, or first memory and uses at least one of the memory bridge or the at least one memory, when transmitting the electric signal. For example, the at least one processor may exchange information via a circuit path that includes the at least one of the memory bridge and a portion of the at least one memory, when transmitting the electric signal.

The at least one processor transmits an electric signal to at least one of the first memory, the I/O interface, the display, or the communication interface.

In accordance with another aspect of the present disclosure, a method of operating such exemplary electronic device is disclosed.

DETAILED DESCRIPTION

Hereinafter, exemplary embodiments of the present disclosure are described in detail with reference to the accompanying drawings. While the present disclosure may be embodied in many different forms, specific embodiments of the present disclosure are shown in drawings and are described herein in detail, with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the specific embodiments illustrated. The same or like reference numbers are used throughout the drawings to refer to the same or like parts.

The expression “comprising” or “may comprise” used in the present disclosure indicates presence of a corresponding function, operation, or element and does not exclude the addition of at least one other function, operation, or element. Further, in the present disclosure, the term “comprise” or “have” indicates presence of a characteristic, numeral, step, operation, element, component, or combination thereof described in this specification and does not exclude the presence or addition of at least one other characteristic, numeral, step, operation, element, component, or combination thereof.

In the present disclosure, an expression “or” includes any combination or the entire combination of together listed words. For example, “A or B” may include A, B, or A and B.

An expression of a first and a second in the present disclosure may represent various elements of the present disclosure, but does not limit corresponding elements. For example, the expression does not limit order and/or importance of corresponding elements. The expression may be used for distinguishing one element from another element. For example, both a first user device and a second user device are user devices and represent different user devices. For example, a first constituent element may be referred to as a second constituent element without deviating from the scope of the present disclosure, and similarly, a second constituent element may be referred to as a first constituent element.

When it is described that an element is “coupled” to another element, the element may be “directly coupled” to the other element or “electrically coupled” to the other element through a third element. However, when it is described that an element is “directly coupled” to another element, no element may exist between the element and the other element.

Terms used in the present disclosure are not to limit the present disclosure but to illustrate exemplary embodiments. When used in a description of the present disclosure and the appended claims, a singular form includes a plurality of forms unless it is represented differently explicitly

Unless differently defined, entire terms including a technical term and a scientific term used here have the same meaning as a meaning that may be generally understood by a person of common skill in the art. It should be understood that generally using terms defined in a dictionary have a meaning corresponding to that of a context of related technology and are not analyzed as an ideal or excessively formal meaning unless explicitly defined.

Herein, when any chip (or element) is said to “exchange an electric signal” or the like, the chip may be either a source of a signal that is transmitted from the chip to another chip or to an external device, a recipient of a signal transmitted from another chip or an external device, or the chip may just provide a passive conductive path for a signal being transferred through the chip, or the chip may perform any combination of these functions.

FIG. 1 is a block diagram illustrating a configuration of an electronic device 5 including a semiconductor device according to an exemplary embodiment of the present disclosure.

The electronic device 5 may include a processor 1, a universal memory bridge 2, a memory 3, an input and output (I/O) interface (not shown), a display (not shown), and a communication interface (not shown). The processor 1, universal memory bridge 2, and memory 3 are packaged in a semiconductor device to be included in the electronic device. The memory 3 may be comprised of plural memories 3 a-3 n (where n refers to any integer greater than one), where each memory 3 a-3 n may be formed as a separate memory chip. Alternatively, memory 3 may be a single memory composed of a single memory chip.

The processor 1 may read information from memory 3 through the universal memory bridge 2 and/or may write information to memory 3. Processor 1 may receive an instruction from other constituent elements (e.g., memory 3, the I/O interface, the display, and the communication interface), decode the received instruction, and execute operation and data processing according to the decoded instruction. (Examples of these components are shown in FIG. 7 discussed later.)

The memory 3 may store an instruction or data received from (or generated by) the processor 1 or other constituent elements (e.g., the I/O interface, display, and communication interface). Memory 3 may include, for example, a programming module such as a kernel 3 r, middleware 3 q, an Application Programming Interface (API) 3 p, and/or an application 3 o. The foregoing respective programming modules may be formed with software, firmware, hardware, or a combination of at least two thereof.

The kernel 3 r may control or manage a system resource (e.g., processor 1 or memory 3) used for executing operation or a function implemented in the remaining programming modules, for example, the middleware 3 q, the API 3 p, or the application 3 o. Further, the kernel 3 r may provide an interface that can control or manage an individual constituent element of the electronic device in conjunction with the middleware 3 q, API 3 p, or application 3 o.

The middleware 3 q may perform an intermediary function of enabling the API 3 p or the application 3 o to send and receive data by communicating with the kernel 3 r. Further, the middleware 3 q may control (e.g., schedule or load balance) a work request received from the application 3 o using, for example, a method of aligning a priority that may use a system resource (e.g., the processor or the at least one memory 3 a-3 n) of the electronic device to at least one of the applications 3 o.

The API 3 p is an interface that enables the application 3 o to control a function in which the kernel 3 r or the middleware 3 q provides and may include, for example, at least one interface or function (e.g., instruction) for file control, window control, image processing, or text control.

In an exemplary embodiment, the application 3 o may include a Short Message Service (SMS)/Multimedia Message Service (MMS) application, e-mail application, calendar application, alarm application, health care application (e.g., application that measures an exercise amount or blood sugar), or environment information application (e.g., application that provides atmospheric pressure, humidity, or temperature information). Additionally or alternatively, the application 3 o may be an application related to information exchange between the electronic device and an external electronic device. The application related to information exchange may include, for example, a notification relay application that transmits specific information to an external electronic device or a device management application that manages an external electronic device.

For example, the notification relay application may include a function of transmitting notification information that has occurred in other applications (e.g., an SMS/MMS application, e-mail application, health care application, or environment information application) of the electronic device to an external electronic device. Additionally or alternatively, for example, the notification relay application may receive notification information from an external electronic device and provide the notification information to a user. For example, the device management application may manage (e.g., install, delete, or update) turn-on/turn-off of a function (e.g., an external electronic device (or a partial component)) of at least a portion of an external electronic device that communicates with an electronic device or brightness of a display (or resolution adjustment), an application operating in an external electronic device, or a service (e.g., a communication service or a message service) provided in an external electronic device.

In an exemplary embodiment, the application 3 o may include an application designated according to an attribute (e.g., a type) of an external electronic device. For example, when the external electronic device is an MP3 player, the application 3 o may include an application related to music reproduction. Similarly, when the external electronic device is a mobile medical device, the application 3 o may include an application related to health care. In an exemplary embodiment, the application 3 o may include at least one of an application designated for the electronic device 5 or an application received from an external electronic device.

The I/O interface (e.g. 140 in FIG. 7) may transfer an instruction or data input by a user through an input and output device (e.g., a sensor, keyboard, or touch screen) to the processor 1, the at least one memory 3 a-3 n, and the communication interface. For example, the I/O interface may provide data about a user touch input through a touch screen to the processor 1.

The display (e.g. 150 in FIG. 7) may display various information (e.g., multimedia data or text data) to the user.

The communication interface (e.g. 160 in FIG. 7) may connect communication signals between the electronic device 5 and the external device. For example, the communication interface may support network communication (e.g., Internet, a Local Area Network (LAN), a Wide Area Network (WAN), a telecommunication network, a cellular network, a satellite network, or a Plain Old Telephone Service (POTS)), short range communication (e.g., Wireless Fidelity (WiFi), Bluetooth (BT), or Near Field Communication (NFC)), or wire communication (e.g., Universal Serial Bus (USB), High Definition Multimedia Interface (HDMI), Recommended Standard 232 (RS-232), or POTS). In an exemplary embodiment, a protocol for communication between the electronic device 5 and the external device (e.g., a short range communication protocol, network communication protocol, or wire communication protocol) may be supported in at least one of the API 3 p or the middleware 3 q.

The processor 1 may be an application processor and may exchange information with the memory 3 through the universal memory bridge 2 using a memory I/O interface.

The memory 3 may include at least one of an internal memory and an external memory. Memory 3 may exchange information with the processor 1 through the universal memory bridge 2 using a wide I/O interface.

The internal memory may include, for example, at least one of a volatile memory (e.g., a Dynamic RAM (DRAM), Static RAM (SRAM), or Synchronous Dynamic RAM (SDRAM)), non-volatile memory (e.g., a One Time Programmable ROM (OTPROM), Programmable ROM (PROM), Erasable and Programmable ROM (EPROM), Electrically Erasable and Programmable ROM (EEPROM), Mask ROM, or Flash ROM), hard disk drive (HDD), or solid state drive (SSD).

The external memory may include at least one of a Compact Flash (CF), Secure Digital (SD), Micro Secure Digital (Micro-SD), Mini Secure Digital (Mini-SD), extreme Digital (xD), and memory Stick.

The universal memory bridge 2 may electrically connect the processor 1 and the memory 3 and provide an interface in which the processor 1 and memory 3 having different input and output interfaces can exchange information.

The universal memory bridge 2 may perform a memory controller function of performing or controlling Error Checking and Correction (ECC), refresh, and test operations of memory 3. Universal memory bridge 2 is termed “universal” because it may interface with different types of memory chips and/or different memory chip sizes.

FIG. 2 is a cross-sectional view illustrating a semiconductor device, designated as 100, according to an exemplary embodiment of the present disclosure. Semiconductor device 100 may operate as a processor module in some embodiments, and in these cases, it may be called a processor module.

The semiconductor device 100 may include a plurality of semiconductor chips 10 a, 10 b, 20 a, and 30 a that may each exchange an electric signal. Semiconductor device 100 may include one or more memory chips 10 a and 10 b that each exchange an electric signal, a processor 10 c, a dummy chip 20 a, and a universal memory bridge 30 a. Memory chips 10 a and 10 b, processor 10 c, dummy chip 20 a, and universal memory bridge 30 a may exchange an electric signal over a partial region and may be connected on a board 40 a. According to an exemplary embodiment, the semiconductor device is connected to the universal memory bridge 30 a to be connected to an external device (e.g., an external memory device). Further, semiconductor device 100 is illustrated as comprising a vertical stack (commonly referred to a “Z” direction stack) of chips so as to provide a 3D fabrication structure, e.g., a 3D package or 3D integrated circuit (IC).

In the example of FIG. 2 and other figures described below, various chips such as 10 a, 10 b, 10 c are exemplified as memory chips or processor chips. However, other types of chips may be utilized in the semiconductor devices, additionally or alternatively to those described.

The dummy chip 20 a is a semiconductor chip that is devoid of active components such as transistors, and that exchanges an electric signal between the stacked memory chips 10 a and 10 b, processor 10 c, dummy chip 20 a, and universal memory bridge 30 a. Any dummy chip as described herein may be a semiconductor chip that only performs a passive connection function. The dummy chip 20 a may include at least one TSV. Memory chips 10 a and 10 b, processor 10 c, dummy chip 20 a, and universal memory bridge 30 a may exchange an electric signal via at least one conductive bump 50 a-50 r formed at one surface of the respective component(s).

Herein, when a conductive bump is said to be formed or disposed “at one surface” or “at a surface”, the conductive bump may be a finally formed bump between a first surface of a first chip and an adjacent surface of a second chip. For instance, a single conductive bump 50 d is shown to exist between the lower surface of chip 10 a and the upper surface of chip 10 b; this conductive bump may be said to be formed at one surface of either chip 10 a or chip 10 b. Prior to a fusing fabrication process step, any conductive bump may comprise a first portion on the first surface of the first chip and a second portion on the adjacent surface of the second chip, which are then fused under a high temperature process to form the final bump such as 50 d.

Power sources may be separately connected to memory chips 10 a and 10 b using power source lines 70 a and 70 b, respectively. With the top end of power line 70 a landing at a point laterally displaced from the conductive bumps at the bottom surface of chip 10 a, metallization (not shown) on or near the top surface of chip 10 b may connect power line 70 a to a bump such as 50 d to provide power to chip 10 a. Likewise, metallization on or near the top surface of chip 10 c may be used to connect power line 70 b to a bump such as 50 j at the bottom surface of chip 10 b to provide power to chip 10 b. Thus, power sources may be separately connected to memory chips 10 a and 10 b using the power source lines 70 a and 70 b, respectively, and in order to exchange an electric signal using the conductive bumps 50 a, 50 b, 50 c, 50 d, 50 g, 50 h, 50 i, and 50 j formed at a surface, circuit surfaces 11 a and 11 b may be formed to face downward (e.g., a direction towards the board 40 a stacked in a lowermost layer). The power source lines 70 a and 70 b may be used for supplying power and may be used as an electric signal line. The conductive bumps 50 c and 50 d may be used for supplying power via connection to the power source line 70 a, as noted above. These bumps may also be used as part of an electric signal line, i.e., as part of an electric circuit. Memory chips 10 a and 10 b and the processor 10 c may be disposed in a step form for a power source line. In other words, the top surface of chip 10 b is shown to extend laterally from the right edge of chip 10 a, and the top surface of chip 10 c is shown to extend laterally from the right edge of chip 10 b, thus forming a step-like structure to facilitate wire connection of the power lines 70 a, 70 b.

In order to exchange an electric signal using the conductive bumps 50 o, 50 p, 50 q, and 50 r formed at a surface, the processor 10 c may be formed such that a circuit surface 11 c faces downward (e.g., a direction towards the board 40 a stacked in a lowermost layer).

In order to exchange an electric signal using the conductive bumps 50 o, 50 p, 50 q, and 50 r formed at a surface, the board 40 a may be formed such that the lower circuit surface 11 c is adjacent an upper metalized surface 41 a of board 40 a. The board 40 a is a portion that becomes a base of the stacked chips 10 a, 10 b, 10 c and the universal memory bridge 30 a. Memory chips 10 a and 10 b, the processor 10 c, the dummy chip 20 a, and the universal memory bridge 30 a may receive power through the board 40 a or may be connected to an external device. The board 40 a may be a printed circuit board (PCB) or may have various forms such as an interposer (intermediate circuit board, e.g., silicon interposer). A plurality of balls 39 are disposed on the bottom surface of board 40 a, which may be part of a ball grid array, enabling individualized connections of designated circuit points to circuit points of an external device(s).

For example, the first memory 10 a may receive separate power using the conductive bumps 50 c and 50 d that make contact with the second memory 10 b and the first power source line 70 a, which connects the second memory 10 b and the board 40 a. The second memory 10 b may receive separate power using the conductive bumps 50 i and 50 j that contact with the processor 10 c and the second power source line 70 b, which connects the processor 10 c and the board 40 a.

In an exemplary embodiment, the first memory 10 a may exchange an electric signal with the dummy chip 20 a through at least one conductive bump 50 a and 50 b disposed at the bottom surface thereof. The second memory 10 b may exchange an electric signal with the universal memory bridge 30 a through at least one conductive bump 50 g and 50 h disposed at the bottom surface thereof.

When an electric signal is transmitted to at least one conductive bump 50 a, 50 b, 50 c, and 50 d disposed at the bottom surface of the first memory chip 10 a, the dummy chip 20 a may transmit an electric signal to at least one TSV 60 a and 60 b connected to the at least one conductive bump 50 a and 50 b.

The dummy chip 20 a may transmit an electric signal received from the at least one TSV 60 a and 60 b therein to the universal memory bridge 30 a through at least one conductive bump 50 e and 50 f disposed at the bottom surface thereof.

The universal memory bridge 30 a may receive an electric signal through the at least one conductive bump 50 e and 50 f disposed at the top surface of the dummy chip 20 a and the at least one conductive bump 50 g and 50 h disposed at the bottom surface of the second memory 10 b. The universal memory bridge 30 a may transmit an electric signal to at least one TSV 60 c and 60 d connected to the at least one conductive bump 50 g and 50 h. At least one TSV 60 c and 60 d included in the universal memory bridge 30 a may not be directly connected to the at least one conductive bump 50 g and 50 h.

The universal memory bridge 30 a may comprise an I/O interface that can interconvert the at least one memory 10 a, 10 b and the processor 10 c having different input and output interfaces. The universal memory bridge may comprise an I/O interface that can interconvert an external memory device, connectable to board 40 a, and the at least one memory 10 a, 10 b.

The universal memory bridge 30 a may transmit information received from the first memory 10 a and the second memory 10 b to the board 40 a through at least one conductive bump 50 k, 50 l, 50 m, and 50 n and receive information received from the processor 10 c through at least one conductive bump 50 k, 50 l, 50 m, and 50 n connected to the board 40 a.

In this case, the universal memory bridge 30 a may be formed with a top circuit surface 31 a (e.g., facing a direction towards the first memory 10 a stacked in an uppermost layer). When the circuit surface 31 a is formed to face upward, the universal memory bridge 30 a may include the second memory 10 b and the at least one TSV 60 c and 60 d that transmit information. In other words, a portion of the second memory 10 b may act as a bridge from the processor 10 c to the first memory 10 a. Further, the metalized surfaces (circuit surfaces) 31 a, 11 b and 11 a may each be patterned an orthogonal or skewed direction to a plane of the shown cross section, so as to connect desired connection points of memory 10 b to desired connection points of memory 10 a, through bridge 30 a and dummy chip 20 a. In this manner, processor 10 c may be communicatively coupled in a circuit to memory 10 a through memory 10 b, bridge 30 a and dummy chip 20 a.

The universal memory bridge 30 a performs a function of interconverting different kinds of memory interfaces at the circuit surface 31 a. For example, the universal memory bridge 30 a may transmit and receive data to a random memory interface (e.g., WIDE-IO interface) through the conductive bumps 50 e and 50 f connected to the dummy chip 20 a, convert the data with different kinds of memory interfaces (e.g., LPDDR series), and transmit and receive data of a converted from to the board 40 a through the TSVs 60 c and 60 d. In the above description of semiconductor device 100, connections at a single cross sectional location have been described. In implementations utilizing parallel data transfer mechanisms, the connections of FIG. 2 may occur repetitively in a direction orthogonal or skewed to the shown cross section. By way of example, in a WIDE-IO interface, parallel data connections to achieve upwards of 512-bit parallel data exchange may comprise a similar order of TSVs and bumps in the orthogonal direction.

FIG. 3 is a cross-sectional view illustrating a semiconductor device, 100′, according to another exemplary embodiment of the present disclosure. Semiconductor device 100′ may include a plurality of semiconductor chips 10 a, 10 b, 20 a, and 30 a that exchange an electric signal. One major difference between the above-described device 100 is the provision of additional TSVs 60 e and 60 f within memory bridge 30 a, which are used to convey signals between the uppermost memory chip 10 a and the board 40 a.

The semiconductor device 100′ may include one or more memory chips 10 a and 10 b, a processor 10 c, a dummy chip 20 a, and a universal memory bridge 30 a that exchange an electric signal. Memory chips 10 a and 10 b, the processor 10 c, the dummy chip 20 a, and the universal memory bridge 30 a may exchange an electric signal over a partial region and may be connected on a board 40 a. According to an exemplary embodiment, various chips of semiconductor device 100′ are connected to the universal memory bridge 30 a which is connectable to an external device (e.g., an external memory device) through board 40 a (where the external device may be connected to balls 39).

The dummy chip 20 a is a semiconductor chip that exchanges an electric signal among the stacked memory chips 10 a and 10 b, the processor 10 c, and the universal memory bridge 30 a. The dummy chip 20 a may include at least one TSV. Memory chips 10 a and 10 b, the processor 10 c, the dummy chip 20 a, and the universal memory bridge 30 a may exchange an electric signal via at least one conductive bump 50 a-50 r formed at one surface.

Power sources may be separately connected to the memory chips 10 a and 10 b using power source lines 70 a and 70 b, respectively, as described above for device 100 of FIG. 3, thus redundant description thereof is omitted here. In order to exchange an electric signal using the conductive bumps 50 o, 50 p, 50 q, and 50 r formed at one surface, the processor 10 c may be formed such that a circuit surface 11 c faces downward (e.g., towards a direction of the board 40 a stacked in a lowermost layer).

In order to exchange an electric signal using the conductive bumps 50 o, 50 p, 50 q, and 50 r formed at one surface, the board 40 a may be formed such that the circuit surface 11 c faces upward (e.g., a direction of the first memory 10 a stacked in a uppermost layer). As described above for semiconductor device 100, board 40 a is a portion that likewise becomes a base of the stacked chips of device 100′, i.e., chips 10 a, 10 b, 10 c, 20 a and the universal memory bridge 30 a. Memory chips 10 a and 10 b, the processor 10 c, the dummy chip 20 a, and the universal memory bridge 30 a may receive power through the board 40 a in the manner described above, or may be connected to an external device.

In an exemplary embodiment, the first memory 10 a may exchange an electric signal with the dummy chip 20 a through the at least one conductive bump 50 a, 50 b, 50 c, and 50 d disposed at one surface thereof. The second memory 10 b may exchange an electric signal with the universal memory bridge 30 a through the at least one conductive bump 50 g, 50 h, 50 i, and 50 j disposed at one surface thereof.

When an electric signal is transmitted to the at least one conductive bump 50 a, 50 b, 50 c, and 50 d disposed at one surface of the first memory chip 10 a, the dummy chip 20 a may transmit an electric signal to at least one TSV 60 a and 60 b connected to the at least one conductive bump 50 a, 50 b, 50 c, and 50 d.

The universal memory bridge 30 a may transmit an electric signal to at least one TSV 60 c, 60 d, 60 e, and 60 f connected to at least one conductive bump 50 g and 50 h. As noted earlier, semiconductor device 100′ differs from device 100 via the inclusion of TSVs 60 e, 60 f which may be used to transfer signals to and from board 40 a and memory 10 a, in electrical paths that include TSVs 60 a, 60 b, respectively, of dummy chip 20 a. To this end, metallization 41 a on the top surface of board 40 a, may be patterned in the orthogonal or skewed direction of the shown cross-sectional view (e.g. in the direction into the paper) so as to enable individualized electrical connections between desired points of the board 40 a and the memory chip 10 a.

TSVs 60 a, 60 b each serve as a portion of a circuit path between a respective connection point of memory 10 a and board 40 a. For instance, TSV 60 a is connected in series with TSV 60 d within memory bridge 30 a, to thereby connect a desired circuit point on memory 10 a to a desired circuit point on board 40 a.

Power sources may be separately connected to the at least one memory 10 a and 10 b using power source lines 70 a and 70 b, respectively, in the same manner described above for semiconductor device 100 of FIG. 2, thus redundant description thereof is omitted. In order to exchange an electric signal using conductive bumps 50 l, 50 m, 50 n, and 50 o formed at one surface, the processor 10 c may be formed such that a circuit surface 11 c faces downward (e.g., a direction of the board 40 a stacked in a lowermost layer).

In order to exchange an electric signal using conductive bumps 50 m, 50 n, 50 o, and 50 p formed at one surface, the board 40 a may be formed such that the circuit surface 11 c faces upward (e.g., a direction of the first memory 10 a stacked in a uppermost layer). The board 40 a is a portion that becomes a base of the stacked at least one memory 10 a and 10 b, the processor 10 c, and the universal memory bridge 30 a, and the at least one memory 10 a and 10 b, the processor 10 c, and the universal memory bridge 30 a may receive power through the board or may be connected to an external device.

The second memory 10 b may receive separate power using conductive bumps 50 g and 50 h that contact with the processor 10 c and the second power source line 70 b that connects the processor 10 c and the board 40 a. The at least one memory 10 a and 10 b and the processor 10 c may be disposed in a step form for a power source line.

In an exemplary embodiment, the first memory 10 a may exchange an electric signal with the universal memory bridge 30 a through at least one conductive bump 50 a, 50 b, 50 c, and 50 d disposed at one surface thereof. The second memory 10 b may exchange an electric signal with the universal memory bridge 30 a through at least one conductive bump 50 e, 50 f, 50 g, and 50 h disposed at one surface thereof.

When an electric signal is transmitted to at least one conductive bump 50 a, 50 b, 50 c, and 50 d disposed at one surface of the first memory chip 10 a, the second memory 10 b may transmit an electric signal to at least one TSV 60 a and 60 b connected to at least one conductive bump 50 e, 50 f, 50 g, and 50 h.

The universal memory bridge 30 a may transmit an electric signal received through at least one conductive bump 50 i, 50 j, 50 k and 50 l disposed at one surface thereof. The universal memory bridge 30 a may transmit an electric signal to the at least one TSV 60 c and 60 d connected to at least one conductive bump 50 i, 50 j, 50 k and 50 l.

The universal memory bridge 30 a may transmit information received from the first memory 10 a and the second memory 10 b to the board 40 a through at least one conductive bump 50 i, 50 j, 50 k, and 50 l and receive information received from the processor 10 c through the at least one conductive bump 50 i, 50 j, 50 k, and 50 l connected to the board 40 a. Metallization 41 a of board 40 a, and metallization 11 c of processor chip 10 c, are each patterned in the direction orthogonal to the cross sectional view shown, so as to isolate circuit points for individualized connection to other points. Thereby, designated circuit points of processor chip 10 c are connectable to respective circuit points of memory 10 a through circuit paths that include TSVs such as 60 c, 60 d within memory bridge 30 a and 60 a, 60 b within the second memory 10 b. Accordingly, a memory bridge between first memory 10 a and board 40 a/processor 10 c can be considered to include both the universal memory bridge 30 a and a portion of the second memory 10 b for transmitting information therebetween.
